TRICK-PIPE Specification oi? Letters Patent.

Patented April 7, 1908.

Application filed November 15, 1907. Serial No. 402,308.

To all whom it may concern:

Be it known that I, FRED I. JUDsoN, residing at Houston, in the countyof Harris and State of Texas, have invented a new and ImprovedTrick-Pipe, of which the following is a specification.

This invention has for its object to provide a simple and interestingtoy inthe nature of a trick or puzzle pipe, having a lid looselysupportable on the bowl, in such manner that under a proper adjustmentof the blowing devices, it can be readily lifted or blown off, and whichunder another adjustment of the blowing the bowl as the user blows intothe stem.

In its generic nature, my invention comprehends a body, preferablyof theshape of a pipe bowl, that has a plurality of vertically extended airpassages that discharge through the bowl top, a lid adapted to rest onthe bowl, and a blowing stem for cooperating with the air passages inthe bowl, so that under a known adjustment it will direct the air blastagainst the lid with such force to lift or blow it off, and whenadjusted to the trick or unknown (to the user) position it will directthe air against the lid in such manner as to create a reduction of theatmospheric pressure between it and the bowl top so it will remainseated thereon by suction, even when the bowl is inverted. during[ theblowing operation.

t its more com lete nature, my invention embodies a bowl shaped bodyhaving a central or main air passage and a supplemental air passage thatdischar es through the top of the centrally balanced id, adapted to restloosely upon the bowl, and a blowing stem having its ejecting end soshaped whereby, under one adjustment it will direct the air through thecentral air passage in a whirling direction and in such manner againstthe lid that it will discharge laterally from under the lid andcreating, as it were, a reduction of atmospheric pressure between thebowl and the lid, thus holding the lid, by suction, from blowing OE, andwhen adjusted to another adjustment it will direct the air through theair passages under its full force against the lid and lift or blow thesame from the bowl, invisible supplemental means being also provided forclosing off a direct blast against the lid.

In its more subordinate features, my in vention consists in certaindetails of condevices will remain seated upon of which will behereinafter fully described and pointed out in the appended claims andillustrated in the accompanying drawings, in which Figure 1., is a viewthat illustrates the manner in which the lid is blown ofi when the partsare adjusted as shown in Fig. 4. Fig. 2, is a similar view that showsthe direction of dischargeof the blast when the parts are in theposition shown in Fig. 5. Fig. 3, is a perspective view of my trickpipe. Fig. 4, is a longitudinal section thereof, the blowing stem andthe supplemental valve device being adjusted to provide the lid forblowing it off. Fig. 5, is a view similar to Fig. 4 showing the positionof the parts when arranged so that the lid will not be blown off. Fig.6, is a detail view of the discharge or valve end of the blowing stem.Fig. 7, is a horizontal section on the line 7 7 on Fig. 4.

In carrying out my invention, I make the parts to resemble the ordinarystraight stern pipe, and for economy of manufacture the bowl or bodyportion is of shape and which is ornamented by -an outer casing orjacket of sheet spring metal, which is secured at the upper end to thebowl and is bowed or curved outwardly from the bowl shaped body for apurpose presently exlained.

wood, turned to.

The bowl a is formed with a straight bore a of uniform diameter, whichis hereinafter termed the main air passage, and it also has asupplemental bore or air passage b of smaller diameter than the mainbore a and which with the main bore discharge through the top of thebowl as clearly shown in Figs. I and 5, by reference to which it willalso be seen that the main and supplemental air passages communicatewith the transversely disposed bore 0 that receives the end of theblowing stem d, formed of bamboo or other suitable material.

6 designates a lid of any light material, that has a diameter sufficientto cover the air passages in the bowl, and preferably slightly greaterthan the diameter of the bowl top.

To balance the lid on the top, for preventing the lid accidentallyslipping endwise of the top and also for aiding in breaking up a directair blast through the main air passage, whereby to cause the air towhirl within said passage as it passes to the exit of the said passagea, the said lid is centrally weighted by a pendent member 6 which may bea pin struction and novel combination of parts, all 1 or long studinserted through the top of the lid, and which is of sufficient lengthto extend some distance down into the central air passage a.

The blowing stem d, the construction of the discharge end of which formsan essential feature of my invention, at a point near its dischargingend has an outlet d which when the stem is inserted in the bowl as shownin Figs. 4 and 5, when turned to one position, see Fig. 4, registerswith the sup plemental air passage 1), for directing the main air blastthrough the said passage 6, as indicated in Fig. 4, and against one edgeof the. lid and under suflicient force to lift the said lid, and whenturned to the position shown in Fig. 5 to move out of register with thesaid passage 5 which is then closed by the solid portion d of the stemas clearly understood from Fig. 5. That portion of the stem beyond theoutlet d and diametrically op osite the said outlet is cut outlongitudinaly to form a long discharging port 62 and the inner end ofwhich is increased in depth at opposite sides as atd, the purpose ofwhich will presently ap pear.

The transverse or stem receiving passage in the bowl extends beyond themain air passage 0/ to form a seat a for the inner end of the stem, asshown in Fig. 5, by reference to which it will be seen that when thestem is turned to close off the supplemental air passage 5, the longchannel or port (:1 will register with the main passage a to direct thefull air blast into the said passage a and a ainst the seat a whichforms the inner end of a pocket and causes the air blast to ascendthrough the said passage in a whirl as indicated in Fig. 5 thuspreventing the blast to ascend in a direct stream against the lid, adirect stream of air through the said passage being also partlyprevented by the central pin or weight that extends down centrally ofthe said passage.

By forming the end of the stem as shown and described, it acts as avalve for controlling the air blast through the stem, since whenadjusted as shown in Fig. 4 its outlet port d is in open communicationwith the supplemental air passage 6 and thus directs the main volume ofthe air against the lid at one side of the center, thus breaking itsequilibrium on the bowl and lifting or blowing it off, the action ofblowing off the lid being augmented by reason of part of the blastpassing up the main passage a in two streams that pass through the sidedischarges d see Figs. 4 and 7 of the long port (Z it being understoodthat as the air passes from the ports d in two distinct streams directlyinto the main passage 0/ and not into the pocket (1 there will be nowhirling action and no consequentdecrease of the air pressure under thelid as is the case when the ports are adjusted as in Fig. 5.

As a further means for cutting off the direct air discharge a ainst thelid, I have shown an automatica ly closed valve f in the nature of aslide that works in a socket a and which has a single air port f. Thisvalve is fastened at the outer end to the sprin metal jacket, which, asit assumes its norma shape, draws the slide valve in position as shownin Fig. 5 and closes the passage 5. This valve is more especiallyintended to close off the passage 1) when the first user forgets toadjust the stem when handing the trick to another, and also making itmore difiicult to solve since to-enable one to blow off the lid thevalve f must be adjusted as well as the stem, the former being adjustedto the open position by pressing against the jacket 0 as shown in Fig.4.

My invention will be especially interesting as a trick, since the averae user will be unable to understand why the id will not blow off evenwhen the bowl is turned upside down as indicated by dotted lines on Fig.5.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is

1.
